In which war did the most Americans die?
American Revolutionary War
World War I
The Civil War
World War II
The Civil War remains the deadliest military conflict in American history, and accounted for more American military deaths than the Revolutionary War, World War I, and World War II combined.
Approximately one in four soldiers that went to war never returned home. For more than a century, it was believed that 618,000 men died in the Civil War: 360,000 from the North and 258,000 from the South. But in recent decades, historians raised the number to an estimated 750,000 deaths, mostly blamed on the under-counting of Confederate casualties.
Answer: The correct answer is The Civil War.
